Application led November 18, 1915. Serial No. 62,152.

To all whom' t may concern:

Beit known that I, HARRIE T. NoWoTNY, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new and.useful Improvements in Cord Fasteners for Window Sashes, of which thefollowing is a full, clear, and eX- act description, reference being hadto the accompanying drawings, forming a part hereof. l

My invention has relation to improvements in cord fasteners for windowsashes;

vand it consists in the novel features of construction more fully setforth in the specication and pointed out in the claims. The presentinvention is directed to irnprovements in weighted window-sashes, thatis to say, sashes whichl are balanced'by weights operating in'boXes onthe sides of the window frame, the object of the invention being to soconstructv the sash as to allow the fastening of a new -cable or chainto -which'the weight is secured, in case of breakage of a worn out chainor cable, without the necessity of removing the sash from the winfiwframe, and without disturbing the stop-head between which and theparting strip the sash operates, A-further object is to provide meansfor fastening the end of the cable to the sash with a minimumexpenditure of waste of cable.

vention in connection with the accompany ing drawings, in which- Figure1 represents in inside elevation thev lower left hand corner of a windowframe and sash with my invention applied thereto, parts being brokenaway. Fig. 2 is an enlarged inner face elevation of one corner of thelower sash with my invention applied, parts being broken away; Fig. 3 isan edge view of the sash looking toward the groove which receives thesuspension cable, or a view looking' toward, the right at Fig. 2; Fig. 4is a' horizontal cross-section on the line-4 4 of Fig. 2; Fig. 5 is aplan of the disk or plate covering the cable-loop at the base of thedepression or basin formed for its reception in the sash-frame; and Fig.6

is a plan of the star-disk with a portion" disk showing the manner offorming the prongs which engage the cable coil or loop behind thecove/rf plate shown in Fig. 5.

Referring toy the drawings, F represents the window frame,.S the lowersash, c, c',

'the suspensin cords or cables for the lower the art.

My present improvement being applied to both sashes, a description ofthe invention in connection with one sideof the lower sash will besuiicient for our purpose.

As previously stated, one of the objects sought is to secure the cableto both the sash' S and weight W, with a minimum length of cable. In thepresent embodiment of my invention the weight-carrying end of the cableis fastened to the weight by any suitable means. The opposite or outerend of the cable is passed through the g L. ove m, through the passagen, into the chamber or pocket P formed in the side member of the sash, asingle loop L being formedin the cable, after which the free end isinsertedl In the present embodiment of my invention I employ a prongedstar-shaped or equivalent serrated disk 3 provided with radial arms tvwhich are bent at right angles to the disk to form prongs or teeth,these prongs being embedded or forced into the coil L after which acircular coverplate or disk 4 is placed over the pronged disk 3, saidcover plate being received by the annular seat 1l-disposed about theentrance tothe pocket P and depressed below the face of the sash frame,said plate when in place, coming flush with the outer face of the sash.After that a securing screw s is passed through. the registeringopenings o o of the respective disks, and through the opening of the.coil L, thus anchoring the outen. end of the cable to the sash. In theevnt the cable c breaks, and it'b'ecomes necessary to replace the brokencable with a fresh cable, the operator first detaches the cable "fromthe weight in the weight-box. He then unscrews the screw s and removesthe disks 3 and 4, and pulls out the other portion of the broken cablefrom the front of the sash. To attach a fresh cable, the operator firstdrops a mouse through4 the top of the groove m, drawing the lower end of.the mouse through the passage/n and pocket P and to this end` after it,after Which ties the new cable. He then `the mouseup thereby ldrawingthe cable --afterit through the pocket P, passage n and'. groovem, thelower Vend of the cable being shoved into the socket p, and by slightlyrelairing the tension on the cable, the loop L will form'almostautomatically within the pocket P (or the operator may form such loop inthe event the cable is too stiff to coil automatically), after which thepronged disk 3 and cover disk 4 are applied, 'the screw s reinserted anddriven through the opening of the loop and` firmly screwed in place,

thereby anchoring the outer end of the new groove for the reception ofasuspension cord` and with a pocket communicating with said groove forreceiving one end of the cord, said pocket opening through the frontface of the side of the'sash, a cover plate secured -to the sash, forclosing the pocket, and a serrated member in the rear of the cover platefor enga-glug the end of the cord in the pocket.

2. A windo sash provided with a side i groove for 'ie reception of asuspension cable, and with a 'pocket communicating Gope of this patentmay be obtained for vecents each, byy addressing the cable is securelyanchored inmates;

-Withsaid groove for receiving one end of the cable, a depression in theface ofthe sash atl the outer terminal of the pocket, a serrated diskfor engaging the cable in the pocket, and an outer cover plate depositedin the depression and jointly with the serrated disk setured to thesash, whereby the to the sash.

- 3.,A sliding window sash rovided with a side suspension cable', a pocet formed on the side of the sash oppositethe face of the sash,saidpocket opening outwardly through the face of the sash, a groove formedinthe -sash for receiving the cable, a' passage establishingcommunication between4 the' groove and pocket, a socket leading downwardfrom the pocket for receiving ,the lower'terminal of the cable, thelatter being adapted to beI looped in the pocket, a circular depressionbounding the outer end of the pocket for receiving a cov'er plate 'forthe pocket, a

pronged disk interposed between the cable loop and cover plate, theprongs thereof engaging the said'loop, and a screw traversing the platesand loop and screwed to the sash,
